Summary: The lack of research on the development of high quality cabbage hybrids in the public sector using combining ability estimates, gene action and heterosis motivated the study. In 2019, 30 F1 hybrids were created between 15 cytoplasmic male-sterile lines and 2 testers following a line x tester design. The performance and characteristics of the parent lines and F1 hybrids were evaluated in a randomized block design during the 2019-2020 season. The study revealed that certain parental lines and specific cross combinations showed promising results in terms of combining ability and heterosis.

Summary: Combining halide perovskite NCs with graphene to design heterostructures shows promise for energy applications, optoelectronics, and photocatalysis. Understanding interfacial charge transfer (CT) dynamics is crucial for the optoelectronic applications of perovskite NC-graphene heterostructures. This study investigates the influence of different surface functionalities of graphene on CT dynamics in FAPbBr(3) NCs attached to functionalized graphene heterostructures. Functionalized graphenes, such as graphene oxide (GO) and amino acids (alanine, tyrosine, and cysteine) functionalized GO, were synthesized and their heterostructures with NCs resulted in quenching of the FAPbBr(3) NCs' photoluminescence (PL). The study demonstrates that the rate of CT and charge transfer efficiency strongly depend on the nature of the functionalizing moieties, with cysteine-functionalized graphene showing the highest hole transfer efficiency.

Summary: In this article, the band gap of ternary ZnCdS quantum dots (QDs) is tuned by changing the concentration of the capping ligand, mercaptoacetic acid (MAA). The functionalization of QDs controls their size and band gap, resulting in a blue shift in the absorption and photoluminescence (PL) spectra. The combination of MAA-functionalized QDs and ensulizole sunscreen exhibits a very high energy transfer efficiency (E) of approximately 70%.

Summary: This study demonstrates the incorporation of different concentrations of graphene oxide (GO) into polyacrylic acid (PAA)-doped SnO2 quantum dots (QDs) and examines their catalytic and antibacterial effects. The QDs' optical properties, surface morphologies, crystal structures, elemental compositions, and d-spacings were analyzed. X-ray diffraction patterns revealed the tetragonal configuration of SnO2 and reduced crystallinity upon dopants. Electronic spectra identified a blue shift and a reduction in band gap energy with GO and PAA incorporation. Fourier transform infrared spectra confirmed the presence of functional groups during the synthesis process. The GO/PAA-SnO2 QDs exhibited enhanced catalytic activity and strong bactericidal efficacy against Escherichia coli (E. coli) at higher GO concentrations. Molecular docking studies predicted their potential as inhibitors of beta-lactamase E. coli and DNA gyrase E. coli.
